" Application filed December '6, 1921. Serial No. 520,304.

To all whom it may'concern:

Be' it known-that I, DAVID ALLEN, a citizen of the United States,residing at New York, in the county'of Bronx and State of New York, haveinvented certain new and useful Improvements in Coin-Changing Mechanism,of 'which'the following' 'is a specification.

This 'inventlon relates to change making mechanism for use on vendingmachines or otherwise.

The object of the invention'is to provide a coin controlledmechanicaldeviceconstructvalue of the coin used to operate the deliv-l ed so thatthe mechanism will actuate means for ejecting change for the full amountof the -coin'dep0sited, or the difference between the price of .anarticle delivered and'gthe' ery mechanism.

Another ob 'ect is to provide a simple and eflicient mechanism. of thischaracter including a container in which a plurality of cartons isstacked, each containing the requi site change, the lowermost of whichis ejected with each rotation of the delivery drum and which is soprotected as to prevent surreptitious removal of thecartons.

\Vith these and other objects in 'view', the

invention consistsin certainnovel features of construction ashereinafter shown," described and claimed.

In the accompanying drawings 1 Figure 1 represents a perspective view ofa vending machine equipped with this improved change making device.

Fig. 2 is a longitudinal section through the vending mechanism'with theupper portion broken off for convenience in illustration. I i

Fig. 3 is a horizontal section taken on the line 3--3 of Fig. 2.

Fig. 4 is a detail transverse section taken on the line 4.-4 of Fig. 3.

Fig. 5 is a detail vertical sectional view of the carton containingportion of the device.

Fig. 6 is a perspective view of one end of the delivery drum showing themechanism actuated thereby for ejecting a change carton, and,

Fig. 7 is a perspective view of one of the cartons, with parts brokenout to show its contents.

In the embodiment illustrated, the change making apparatus is shownapplied to avending machine shown at 1 having. mounted therein a rotaryarticle discharge drum 2 which is equipped at 'oneend'with a lug 3,designedwhe'n the drum is turned for as;

livering an article purchased to'enga'ge one end-of a link 4 positionedin thepath "of said lug-and through said link actuate an ejecting lever5'. *T-hislever 5 is fulcrumed .on a suitable support andope'ratesthrough a slot 6 in one wall of the'ca-sing of the vendingmachine, as'is shown clearly'in Fig. 4'. j

The casing 1 oflthe machine has an opening 7 in oneside wall nearitslower portion as isshown clearly in'Figfil and'atray .8 extendslaterally outward from the bottom wall of said opening and ispositioned-'di rectlybelow a container 9 'whichcarries the cartons 10containing thechange.

The container'9:whi'ch ishere shown sef cured to the casing 1 but which"obviously may be locatedon any suitable "support, communicates at itslower end withthe slot 6 through which the lever 5 operates, said" leverbeingdesigned to" move transversely across the lowerendof'said-container for ejecting a carton in; a manner presently v tobe described.

'The' link 4 which operates the of one of the side walls o'fthe casing 1as,

is shown clearly' inFig's. 2 and 3. This link ,lS providedat itsoppositeend with laterally. extending lugs or fingers 11 and 12 arrangedrespectively one in'the' path of the drum? carried lug and the otherloosely engaged with the upstandingarm5 of the lever 5.1

,A coiled spring 13 is connected at one end with the" upstanding arm 5of lever 5 and at its other end with a fixed member'of the The cartoncontalner 9 has an opening 14:

extending throughout the greater portion of the length thereof and whichis preferably covered with a transparent material so that it may bereadily seen whether there are any cartons 1Q in the container.

lever 5 is showirmounted to slide longitudinally in suitable guides lsecured to'the inner face" A protectivecasing 15 is here shown en-;-

material so that the container 9 may be viewed therethrough. This casing-15- also has an opening 17 in the bottom thereof at one side of thecontainer 9 for the discharge.

therethrough of the carton '10ejected by the lever 5.

A movable element here shown as a. coin controlled dispensing drum 2 isrotated when a coin is dropped in the coin slot 18 of the machine andwhen rotated a dis tance suificient to cause lug Bto engagethe lateralextension ll of the link h saidlink'; will be moved longitudinallyforward cans;

ing the ejecting lever, toswing .on its fulcrum and the, arm thereofwhich is located adjacent the container 9 j to swing through the slot 9in said container and eject the carton 1.0.whichis resting on the bottomthereof. This carton will drop into the tray 8 located below it and, maybe takenby the party desiring the change, the; coin used to actna tethedrum andfor which chan e was desired drops into suitably located toreceive it.

a receptacle As shown, the carton contains four,

pennies which is designed to be thechange between the cost of a cigar atsixcen-ts and the coin in the form ofa dime. which is used to actuatethedrum; It is ofcourseun derstood that while this machine is shown for usein vgonnection with a dime and, an article valued at six cents, anyother article may 1 bedeliverkad. thereby and any other coinof 7 anyvaluation desired may be used for operating it, the carton 10'containingthe proper change, or-the full value of the coin when changeonly is desired.

'Afterthedrum 2 has been operated discharge an-article and is released,it will be returned to normal position by; any suitable means, notshown, and when so re turned, the spring 13 will operate tov return thelever 5- to normal position and to position thejlink-Aready foractuationto the next rotation of the drum 2,

It will thus be seen that this change makin .ap paratusis extremelysimple, the-only part liable to become broken or inoperative derstoodthat modifications within the scope:

of the claimed invention-inay bemadein the 'construction or use withoutdeparting from the principle ofthe invention or-sac:

I claim a y l. The combination of a, movable mem her, a lever, a c-hangecontainer having sep arate packages of coins stacked therein andprovided witha discharge opening, acoin ejector pivoted intermed i'atelyof-the ends,

one end movable throu'ghsaid opening and a linkoconne cted Withthe'otherend ofg said lever and positioned in the pathfof said;

movable member whereby when; said "111311 17 ber 1s actuated-1n onedirection, sald llevei will be swung to eject a coin. 1 g

2. The combination ofa movable member, a change. container havingcartons of; coins stacked therein.andprovided at jts lower endwith'a-discharge, opening, means for.

protecting sa-id :opening against surrepti tious removal ofthe cartons,a cart-on ejector 1n the form ofa lever fulcrn-med adjacent saidcontainer, and" adapted to swing through the opening there-1n, saidleverhaving-an upstanding arm, a link engaged with j said arm and mountedin-the path of said movable member whereby the movement 'ofsaid memberin one direction will actuate said lever lZOHBLIGCt a carton, and acoiled spring connected with said arm and with a fixed part of themachine for y-returning sard lever to lilltlal posit on h afteractuation.
